3445-13. Phone operation (Hands-free system for cellular phones)
COROLLA HV_U
●This system is not guaranteed to
operate with all Bluetooth®
devices.
●If your cellular phone does not
support Bluetooth®, this system
cannot function.
●In the following conditions, the
system may not function:
• The cellular phone is turned off.
• The current position is outside the
communication area.
• The cellular phone is not con-
nected.
• The cellular phone has a low bat- tery.
●Depending on the type of Blue-
tooth® phone, some function is
not available.
●When using the hands-free sys-
tem or Bluetooth® audio and
Wi-Fi® Hotspot functions at the
same time, the following problems
may occur:
• The Bluetooth
® connection may
be cut.
• Noise may be heard on the Blue-
tooth
® audio playback.
• A noise may be heard during phone calls.
●Bluetooth® uses the 2.4 GHz fre-
quency band. If both a Wi-Fi® con-
nection and Bluetooth®
connection are being used simul-
taneously, each connection may
be affected.
●If a Bluetooth® device is attempt-
ing to connect to the vehicle while
another device is connected as a
Bluetooth
® audio device or con-
nected using the hands-free sys-
tem or Wi-Fi
® Hotspot function,
the communication speed may
decrease or malfunctions may
occur, such as image distortion or
audio skipping. If a Bluetooth
®
device is connected to the system,
the interference it may cause will
be reduced. When carrying a
device with its Bluetooth
® connec-
tion enabled, make sure to regis-
ter it to the system and connect it
or disable its Bluetooth
® function.
●When a device is connected via
Bluetooth®, the Bluetooth® icon
on the status bar will be displayed

Some basics
The hands-free system
enables calls to be made
and received without having
to take your hands off the
steering wheel.
This system supports Blue-
tooth
®. Bluetooth® is a wire-
less data system that
enables cellular phones to
be used without being con-
nected by a cable or placed
in a cradle.
The operating procedure of
the phone is explained here.
When an Apple CarPlay
connection is established,
phone functions will be per-
formed by Apple CarPlay
instead of the hands-free
system.
